Basics of validating xmls with a given schema in C++.
1. Create parser instance.

SAX2XMLReader* parser = XMLReaderFactory::createXMLReader();

2. Set required features to parser instance as follow.
// Enable the parser’s schema support parser->setFeature(XMLUni::fgXercesSchema, true);
// Schema validation requires namespace processing to be turned on.<br />parser->setFeature(XMLUni::fgSAX2CoreValidation,true);<br />parser->setFeature(XMLUni::fgSAX2CoreNameSpaces,true);

3. Set schema location using setPropery api call with/without namespace. If we want use […]
